Police say one man committed four bank robberies, all on Murray Avenue in Squirrel Hill and Greenfield, even while they had one of those banks under surveillance.

Joseph Guiney Jr., 33, was found Tuesday morning in Penn Hills by the U.S. Marshals Fugitive Task Force. He was arrested and taken to the Allegheny County Jail.

Pittsburgh police said Guiney will be charged with a March 27 robbery at First National Bank, an Oct. 31 robbery at First Niagara Bank and two robberies at Citizens Bank, one from Nov. 9 and another from Saturday afternoon.

Police acknowledge that the Saturday robbery happened at one of seven branches that were under surveillance by roving patrols that day. Somehow, the robber was able to escape anyway.

In Saturday's robbery, bank employees told police that the stick-up man showed them a gun in his waistband and said, "I don't want to do this but I have a problem."

The robber on Saturday also said, "Give it up. You gave it up last week, so give it up again." Police believe he was referring to the Nov. 9 robbery at the same bank.
